[PATCH v2 0/3] target/s390x: vfmin/vfmax fixes

[Ilya Leoshkevich]

Hi,

Uli has found an issue with finding maximum of different kinds of 0s; I
wrote a test and found another one with finding maximum of different
kinds of NaNs.

Patches 1 and 2 fix those issues, patch 3 adds a vfmin/vfmax test.

Best regards,
Ilya

v1: https://lists.gnu.org/archive/html/qemu-devel/2022-07/msg01915.html
v1 -> v2: Drop mmap() in the test (Richard).
